M'IIGLARE ATTACHJHENT FOR HEADLIGH'I'S.

Application filed November 25, 1922. Serial No. 603,281.

To all whom it may concern:

Be it known that I, JAY D. Jones, a. citizen of the United States, and resident of the borough of Manhattan, in the city and State of New York, have invented a new and useful Improvement in Anti lare Attachments for Headlights, of whic the following is a specification.

The object of my invention is to provide a novel anti-glare attachment for lamps, such for instance as automobile head lamps; said attachment to be used in lieu of the usual front lens of the lamp and serving to eliminate the lare by diffusing the light without unduly dimming the same.

My invention comprises an attachment of the above character having a hood which may be adjusted to different angular positions for directin the light rays nearer to or farther away rom the lamp, said hood having a lens covering its front and being provided with a plurality of upwardly and rearwardly inclined vanes of considerable width, permitting them to be spaced a considerable distance apart.

A practical embodiment of my invention is represented in the accompanying drawin s, in Which ig. 1 represents a vertical longitudinal central section through an automobile head lamp of ordinary construction with my improved anti-glare attachment secured in position to the open front of the lamp.

Fig. 2 represents a front view of the lamp.

Fig. 3 represents a detail view showing the bayonet joint connection between the lens securing ring and front or" the hood.

Fig. 4 represents a detail section showing the means for slidably connecting the vanes with the hood.

The head lamp herein shown comprises the usual casing, 1, reflector 2, high power centrally arranged lamp bulb 3 and offset low power auxiliary lamp bulb 4.

The usual front lens for the lamp is omitted and the front rim 5 which ordinarily supports the lens is used as the means for supporting the anti-glare attachment to be immediately described.

The anti-glare attachment is fitted for exterior application to the open front of the lamp and it comprises a ring 6 having an outwardly projected circumferential flange 7 which is clamped between the inwardly turned annular flange 8 of the rim 5 and the stepped flange 9 of the reflector 2, which is held in position by the brackets 10 and fastening screws 11.

A forwardly flarin' hood 12 is mounted on this ring 6 for a justment to different angular positions, in the present instance by providing the ring with a dowel pin 13 projecting upwardly through a hole in the top of the back of the hood 12 and by providing the bottom and sides of the ring 6 with projecting portions 14, having clamping screws 15 which pass through elongated slots 16 in the bottom and sides of the back of the said hood 12. The front of the hood 12 is covered by a lens 17 which is held in position by a ring 18 having bayonet joint connections 19, 20, with the front of the said hood. This hood 12 is provided with a plurality of upwai dly' and rearwardly inclined vanes 21 of considerable width and spaced a considerable distance apart, said vanes being preferably of transluicent material. The front edges of these vanes lie in substantially the front plane of the hood adjacent to the lens 17 and their rear portions project through the open frontv of the lamp to bring their rear edges within the reflector 2, to the desired points with respect to the lamp bulbs 3 and 4.

By making these vanes of considerable width effectual screening of the light rays is obtained without the necessity of using too many vanes which serve to close up the the light openings and materiall dim the light rays. Furthermore b ma ing these vanes of translucent materia an undue dimming of the light rays is also obviated.

I have represented these vanes as removable, in the present instance by a sliding movement by providing the inner side wal surface of the hood 12 with guides 22 having their forward ends closed and their rear ends opened. A means is thus provided whereby any of the vanes may be immediately removed for cleaning, replacement or other purpose.

The front of-the hood at its top is rovided with a plate 23 immediately bac of the lens 17 for screening the light rays at this point, in which screen plate ll locate a bulls eye lens 24, through which light rays from the auxiliary lamp 4 will be pro ected.

It will be seen that by mounting the antlglare attachment on the open front of the lamp, it may be attached to lamps of ord1- nary construction. It may also be readily removed with the front rim of the lamp for gaining access to the lamps, vanes and reflector.

The anti-glare attachment constructed ac cording to my invention will be very strong and durable and will let the maximum light therethrough with an entire elimination of the glare from the lamps, the attachment at the same time being very simple m construction and inexpensive to manufacture.

It is evident that various changes may be resorted to in the construction, form and arrangement of the several parts without departing from the spirit and scope of my invention, hence I do not wish to be limited to the particular embodiment herein shown and described, but

What I claim is 1. An exterior anti-glare attachment adapted to be secured to the open front of a head lamp, said attachment comprising a hood and a plurality of upwardly and rearwardly inclined vanes leading rearwardly from the front of the hood to points within the reflector back of the open front of the lamp, and a lens covering the front of the hood.

2. An exterior anti-glare attachment adapted to be secured to the open front of a head lamp, said attachment comprising a hood and a plurality of upwardly and rearwardly inclined vanes of considerable Width and spaced a considerable distance apart, leading rearwardly from the front of the hood to points Within the reflector back of the open front of the lamp, and a lens covering the front of the hood.

3. An exterior anti-glare attachment adapted to be secured to the open front of a head lamp, said attachment comprising a hood and a plurality of upwardly and rearwardly inclined vanes leading rearwardly from the front of the hood to points within the reflector back of the open front of the lamp, and a lens covering the front of the hood, said hood being adjustable to difi'erent angular positions.

4. An exterior anti-glare attachment adapted to be secured to the open front of a head lamp, said attachment comprising a hood and a plurality of upwardly and rearwardly inclined vanes of considerable width and spaced a considerable distance apart, leading rearwardly from the front of the hood to points within the reflector back of the open front of the lamp, and a lens covering the front ot the head, said aneaeea hood being adjustable to different angular positions.
